Restoration & Refurbishment- 18 Apr 2026
I had my bathroom fully tiled and refurbished by Mr Madan and it was done with patience and professionalism. My house is 1930s build and it comes with its own challenges when doing a project, but Mr Madan dealt with every challenge, whilst keeping my costs down. I'm 100% happy with the end result and I will highly recommend him.
